SADDLE-SUPPORT.

Specification of Letters Patent.

Patented Nov. 15, 1910.

Application filed July 1, 1910. Serial No. 569,893.

To all whom 'it may concern.'

Be it known that I, EMERSON H. PINK- HAM, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of N ewl York, have invented a new and Improved Saddle-Support, of which the following is a full, clear, and eXact description.

The invention is an improvement in cycle saddle supports, more especially for motor cycles, and lias in View a yielding support with which the saddle moves rearwardly, and is depressed at both the front and rear under shock, and is returned forwardly and raised by the recoil to normal position. To this end the front portion of the saddle is slidably supported between shock-absorbing and recoil springs on a downwardly and rearwardly-inclined guide, and the rear portion of the saddle supported on cushion posts fulcrumed at their lower ends to swing forwardly and rearwardly.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters' of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the rear portion of a motor cycle, showing my iinproved saddle support; Fig. 2 is a longitudinal vertical section through the forward portion of the support, showing the shockabsorbing` and recoil springs; Fig. 3 is a plan of the support partly in section; Fig. 4 is a central vertical section through one of the cushion saddle posts; and Fig. 5 is-a cross-section through the forward portion of the support immediately at the front of the slide.

For the purpose of illustrating the nature and application of my improvements, I have shown a motor cycle having a common form of bicycle frame embodying what is commonly the saddle post 5, which, in the present instance, is provided with a downwardly and rearwardly-inclined guide 6, the latter, as best shown in Fig. 5, being made up of two L-shaped or angle irons 7 secured to the post by a number of cross-bolts 8. Seating on the guide 6 and engaging under the flanges of the angle-irons is a slide 9 having outwardly-extending pivot pins 10, and also provided with an upwardly-extending central lug 11, on which the front of the saddle is supported through the intermediary of a lug 12, the saddle 13 in the present instance being Of a well-known type.

Fulcrunied to the frame, shown to be substantially radially of the rear wheel of the machine, to swing forwardly and rearwardly, are cushion posts 111, 14, each post,

as best shown in Fig. 4t, being made up of an outer and inner telescoping tubular section, the inner section being slidable through a cap 15 threaded on the upper end of the outer section, and at its lower end slidable within a close-fitting tube 16 secured in the bottom of the outer section. The inner section of the post at its lower portion also slides over a tube 17, seating within the outer section, the tube 17 inclosing a central screw 18 threaded into the bottom of the lower section and held in place by a lock nut 19. On the screw 18 is an adjustable nut 20 having a projection or key 21 slidable within a slot 22 formed longitudinally of the tube 17.

The inner section of the post 141 is provided with an external collar 23, between which and the tube 16 is interposed a cushion spring 24, the post being further cushioned by a spring 25 interposed between the upper end of the tubular inner section of the post and the nut 20. By the adjustment of the nut 20, the stiffness of each post may be increased or diminished to make thesaddle support suitable for riders of different weights.

To the pivot pins 10 of the slide are connected saddle supporting bars 26, the rear end Of each bar being connected to the upper end of the outer section of the cushion post at the corresponding side o f the frame. The rear portion of the saddle is supported on these bars adjacent to the cushion posts through the intermediary of what are shown to be helical springs 27, these springs, however, not being at all essential, b ut may be dispensed with and the saddle rigidly connected with the supporting bars at these points.

The central lug 11 of the slide 9 is. interposed between a shock-absorbingspring28 and a recoil spring 29, these springs being arranged on a screw-threaded rod over which the lug 11 freely passes, and which is carried by the slide, one end of the rod being screw-threaded and provided with an adjusting nut 30, whereby the tension on the springs may be regulated.

In the use 0f e motor er other @rele eqllliipped with my improved saddle support, wen the machine strikes an obstacle or rough place in the road, the shock causes the saddle to Inove rearwardly againstthe shock-absorbing spring, and at the same time swing back the cushion posts and cause the outer sections thereof to be forced within the lower section, thus both ends of the saddle are caused to drop slightly at the same time; accordingly, the saddle moves in approximately successive parallel planes. On the recoil of the support, the saddle carried to normal position up the inclined plane afforded by the guide, against the tension of the recoil spring. In this manner the rider is carried with little shock or vibration.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

L'The combination of a cycle frame, a

downwardly and rearwardly-inclined guide carried bythe frame, cushion posts fulcrumed to swing forwardly and rearwardly` saddle-supporting members carried on the posts andslidable on the guide, a shockab'sorbing spring forcing the said members forwardly, and va recoil spring forcing the said members rearwardly.

I 42i'. The combination of a cycle frame, a downwardly and rearwardly-inclined guide carried by the frame, a cushion post fuloruined on the frame to swing forwardly and rearwardly, and a saddle slidably supported at its forward portion on the guide and supported at the rear thereof from the post 3Q The combination of a cycle frame, a guide carried by the frame, cushion posts fulcrumed'on the frame to swing forwardly and rearwardly, a slide seating` on the guide, and saddle-supporting bars connected to the posts and to the slide.

t. The combination of a cycle frame, a downwardlyl and rearwardly-inclined guide carried by the frame, a cushion post fulcrumed on the frame to swing forwardly and rearwardly, a slide seated on the guide, a saddlefsupporting member connecting the post to the slide, and a shock-absorbing spring normally forcing the guide forwardly.

5. The combination of a cycle frame, a

l downwardly and rearwardly-inclined guide carried by the frame, a slide seated on the guide, a rod fixed relatively to the guide and passing through the slide, a shock-absorbing spring arranged on the rod and forcing the guide forwardly, a recoil spring arranged on; the rod and forcing the guide rearwardly,

the .red having a eut ter @einstieg the ten sion on the spring, a cushion post fulcrurned to the frame to swing forwardly and rearwardly, and a saddle-supporting bar connecting the guide to the post.

Y 6,. The combination of a cycle frame, means to support the forward portion ofthe saddle from thel frame, and a cushion post to support the rear portion of the saddle, fulcrumed on the frame to swing forwardly and rearwardly, the post having telescoping` sections, with a cushion spring in each section l 7. The combination of a cycle frame, saddle supporting bars movably supported at their forward portions on the frame, and cushion posts fulcrumed on the frame to swing forwardly and rearwardly, each cushion post made of an inner and outer telescoping tubular section, with the inner section connected to one of the said supporting bars, each section of the post having a cushioning spring arranged therein, and the outer section of the post provided with a screw having an adjusting nut arranged to adjust the vtension on the cushioning spring of the inner section of the post.

8. ln a saddle support for motor cycles, a cushion post mounted to swing forwardly and rearwardly and constructed of two telescoping tubular sections, each section having a cushion spring arranged therein, the outer section of the post having a cap at the upper end and a tube at the lower end into which the inner section of the post is slidably fitted, the outer section of the post having a tube projecting from the bottom thereof, telescoping within the inner section of the post and provided with a central screw having a nut, with the nut splined to the lastnamed tube and adjustably supporting the lower end of the cushion spring of the inner section of the post.

9. The combination of a cycle frame, a cushion post fulcrumed at the rear of the frame to swing forwardly and rearwardly, and a saddle supporting bar fulcrumed to the post and operatively supported forwardly thereof on the frame.

l0. In a cycle, a frame, a cushion post fulcrumed to swing forwardly and rearwardly, and a saddle support connecting the upper end of the post to the frame.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
